Stults, Dayton, Ghio, assignor to Dayton Machine Tool Company, Dayton, Ghio, a corporation of Ohio Filed May 27, 1959, Ser. No. 816,323 1 Claim. (Cl. 83145) This invention relates to an improved perforating apparatus, and, in particular, this invention relates to an improved apparatus for cancelling articles by perforating the same.

Heretofore, many types of apparatus have been provided for cancelling articles, such as checks, premium trading stamp books, and the like, whereby the cancelled article cannot be subsequently used as the same readily gives the appearance of being void or cancelled. Certain of the prior known apparatus each comprises a structure whereby the particular article to be cancelled is placed on a support plate of the apparatus and a punch mechanism is moved against the article and forms a plurality of perforations through the article whereby the same is cancelled.

Therefore, it is one of the objects of the present invention to provide an improved apparatus adapted to cancel articles by perforating the same.

It is another object of the present invention to provide an improved apparatus which is relatively inexpensive, rugged, and the like, and which is adapted to force a plurality of punch members through an article received in the apparatus whereby a plurality of openings are formed in the particular article.

Another object of the present invention is to provide an improved apparatus which is relatively inexpensive to manufacture, sturdy, relatively free from expensive maintentance and replacement parts costs, long-lasting, and the like, and which is adapted to manually force a plurality of punch members through an article received in the apparatus with a minimum of effort regardless of whether the article comprises a plurality of sheets of paper, such as a premium trading stamp book or the like, or other perforatable material, such as metal and the like. Other objects, uses and advantages of the present invention will become apparent upon a reading of the following specification taken in conjunction with the accompanying drawing forming a part thereof and where- FIGURE 1 is a side elevation view of an apparatus formed in accordance with the teachings of this invention;

' FIGURE 2, is a fragmentary front view of one of the punch members carried by the apparatus of FIGURE 1;

FIGURE 3 is a fragmentary front view illustrating certain operating parts of the apparatus of FIGURE 1.

FIGURE 4 is a fragmentary cross-sectional view of the apparatus of FIGURE :1 and illustrates the same perforating article and,

FIGURE 5 is a view similar to FIGURE 4 and illustrates the apparatus of FIGURE 1 after the same has perforated the article.

' Reference is now made to the accompanying drawing wherein like reference numerals are used throughout the various figures thereof to designate like parts where appropriate, and particular reference is made to FIGURE 1 illustrating a perforating apparatus formed in accordance with theteachings of this invention and generally indicated by the reference number 10.

The perforating apparatus. includes a frame, generally. indicated by the reference numeral 11, comprising a base plate or member 12 and an upwardly extending support 13. The support 13 may be formed integrally with the base plate 12 or formed separately and secured to the base plate 12 in any feasible manner. The support 13 includes an integral tapering support rib 14 extending from one side thereof and a horizontal plate-like portion 15 projecting from the other side thereof. A substantially cylindrical portion 16 is formed integrally with the support '13 and extends vertically upwardly from the plate-like portion 15. It is to be understood that the various parts 1216 of the frame 11 could be formed separately or integrally as desired.

A lower support plate 17 is secured to the base plate 12 in any feasible manner whereby the plate 17 encompasses a substantially rectangularly-shaped opening 18 passing vertically through the base plate '12. The lower support plate 17 has a pair of opposed flat surfaces 19 and 20* interrupted by a plurality of apertures 21 passing vertically therethrough. It is to be understood that one or more apertures 21 may be provided, if desired, and the apertures 21 could be arranged in any desired pattern.

The perforating apparatus 10 is adapted to be set upright on the base plate 12 in the position illustrated in FIGURE 1 by placing the base plate 12 on a counter, table, or the like. If desired, the perforating apparatus 10 may be supported independently in an upright position on a floor or other surface by respectively securing a pair of inverted U-shaped elements 22 to the opposed ends of the bottom of the base plate 12, the elements 22 being secured to the base plate 12 by a plurality of bolts 23 whereby the depending portions 24 of the U- shaped members 22 provide suitable support legs for the apparatus 10.

A bore 25 is formed vertically through the cylindrical and plate-like portions 16 and 15 of the support 13 and telescopically receives an axially movable cylindrical shaft or rod 26 secured to a horizontally disposed plate 27 and having a free end 28 projecting vertically upwardly through the bore 25.

The upper plate 27 has a pair of opposed flat surfaces 29 and 30 interrupted by a plurality of openings 31 passing vertically through the plate 27 and being adapted respectively to telescopically receive a plurality of knockoff pins 32 projecting vertically downwardly from the plate-like portion 15 of the support 13. Each knockoff pin 32 may be secured tothe support 13 in any desired manner, and in the embodiment illustrated each knock-off pin 32 has a small cylindrical projection 33 received Within a cooperating bore 34 passing vertically through the plate-like portion 15. Each projection 33 of the respective knock-off pin 32 may be press-fitted in the respective bore 34 or fastened therein by welding, soldering, or the like.

A plurality of punch members 35 is suitably secured to the plate 27 and extends vertically downwardly from the lower surface 30 thereof. Each punch member 35 includes an integral projection 36 (see FIGURES 1 and 2) suitably secured within a cooperating bore 37 formed in the plate 27, and a tapering Wedge-like portion 38 adapted to perform the perforating operation later described. It is to be understood that one or more punch members 35 may be utilized as desired, the only factor determining the number of punch members 35 utilized is the number of cooperating apertures 21 formed in the plate 17. Further, the punch members 35 may be arranged in any desired pattern to produce perforations arranged in a particular pattern, such as defining a word or Words or the like.

A pair of spaced lugs 39 extends outwardly from the upper end of, the support 13 of the frame 11 and may be formed integrally therewith or formed separately and secured thereto in any suitable manner. The lugs 39 are disposed parallel to each other whereby an end 40 of a handle 41 is adapted to be received therebetween and pivoted thereto by a suitable pivot shaft 42 passing respectively through suitable apertures formed in one of the lugs 39, the end 40 of the handle 41, and the other lug 39. A substantially triangularly-shaped cam 43 is pivoted to the frame 11 by having one end 44 there of received between the lugs 39 and pivotally secured thereto by a suitable pivot shaft 45 passing through suitable apertures formed respectively in one of the lugs 39, the end 44 of the cam 43, and the other lug 39.

Another end 46 of the cam 43 is pivotally connected to a pair of handle links 47 in the following manner. Each handle link 47 is disposed on a different side of the cam 43 and has an end 48 pivoted to the end 46 of the cam 43 by a suitable pivot shaft 49 passing through suitable apertures formed respectively in the respective handle link 47, the end 46 of the cam 43, and the end 48 of the other handle link 47. Each handle link 47 is disposed on a different side of the handle 41 at a point spaced from the end 40 thereof and is pivotally secured thereto by a suitable pivot shaft 50 passing through suitable apertures formed respectively in the end 51 of the respective handle link 47, the handle 41, and the end 51 of the other handle link 47.

A pair of shaft links 52 interconnect the cam 43 with the free end 28 of the shaft 26 in the following manner. Each shaft link 52 is disposed on a different side of the cam 43 and has an end 53 pivotally secured to the medial depending portion of the cam 43 by a suitable pivot shaft 54 passing through suitable apertures formed respectively in the end 53 of the respective shaft link 32, the cam 43, and the end 53 of the other shaft link 52. The other end 55 of each shaft link 52 is disposed on a different side of the free end 28 of the shaft 26 and is pivoted thereto by a suitable pivot shaft 56 passing through suitable apertures formed respectively in the end 55 of the respective shaft link 52, the free end 28 of the shaft 26, and the end 55 of the other shaft link 52.

In this manner, when the handle 41 is manually grasped and pivoted to the left from the position illustrated in full lines to theposition illustrated in dotted lines in FIGURE 1, the links 47 and 52 and the cam 43 translates the pivotal movement of the handle 41 into axial movement of the shaft 26 whereby the shaft 26 is moved vertically downwardly and thus the plate 27 is moved vertically downwardly toward the other plate 17 of the apparatus 10. Similarly, when the handle 41 is pivoted from the position illustrated in dotted lines to the position illustrated in full lines in FIGURE 1, the links 47 and 52 and cam 43 translates the pivotal movement of the handle 41 into axial movement of the shaft 46 whereby the shaft and plate 27 are moved vertically upwardly away from the plate 17 The operation of the perforating apparatus 1% will now be described. An article, generally indicated by the reference numeral 57 (see FIGURES 4 and is placed on top of the upper surface 19 of the lower support plate 17 when the plate 27 is in its raised position as illustrated in full lines in FIGURE 1. As previously stated, the article 57 may comprise a check, premium trading stamp book, a metal member, orthe like, which is desired to be cancelled by perforating the same. After the article 57 has been placed on the lower support plate 17, the handle 41 is pivoted to the position illustrated in dotted lines in FIGURE 1 whereby the plate 27 is moved vertically downwardly toward the lower support plate '17 in the manner previously described. As shown in FIGURE 4, when the plate 27 is moved downwardly toward the plate 17, the punch members 35 carried by the plate 27 are forced vertically through the article 57 and are respectively received within the cooperating apertures 21 formed in the lower support plate 17. When the lower surface eve-ea 4 30 of the plate 27 makes engagement with the article 57, further movement of the plate 27 vertically downwardly is prevented.

After the article 57 has been perforated in the manner set forth above, the handle 41 is pivoted towards the position illustrated in full lines in FIGURE 1. As the handle 41 is pivoted to the right, the plate 27 is moved vertically upwardly away from the lower support plate 17. However, since the punch members 35 have been forced through the article 57, the article 57 becomes attached to the punch members 35 and is carried upwardly with the plate 27. As the plate 27 moves vertically upwardly, the knock-off pins 32 are respectively received in the openings 31 formed in the plate 27 whereby the knock-off pins 32 subsequently project through the plate 27 against the article 57. As shown in FIGURE 5, the knock-off pins 32 are adapted to force article 57 oif of the punch members 35 whereby the same will drop to the lower support plate 17 and be subsequently removed therefrom.

Therefore, it can be seen that an improved perforating apparatus has been disclosed which is not only relatively inexpensive to manufacture and maintain but that is also adapted to perforate an article with a minimum of effort and time.

While the apparatus 10 has been described as operating with various manual steps, it is'to be understood that it is contemplated that the same could operate automatically, if desired.

While the foregoing presents a preferred embodiment of the invention, it is obvious that modifications and/or equivalents may be employed without departing from the scope of the invention, which is defined in the appended claim.
